TECHNICAL FIELD

The present invention relates to a process for preparing compositions comprising steviol glycosides. The present invention also relates to the use of compositions comprising steviol glycosides as sweeteners and/or flavor enhancers.

BACKGROUND OF THE INVENTION

High intensity sweeteners possess a sweetness level that is many times greater than the sweetness level of sucrose. They are essentially non-caloric and are commonly used in diet and reduced-calorie products, including foods and beverages. High intensity sweeteners do not elicit a glycemic response, making them suitable for use in products targeted to diabetics and others interested in controlling for their intake of carbohydrates.

Steviol glycosides are a class of compounds found in the leaves of Stevia rebaudiana Bertoni, a perennial shrub of the Asteraceae (Compositae) family native to certain regions of South America. They are characterized structurally by a single base, steviol, differing by the presence of carbohydrate residues at positions C13 and C19. They accumulate in Stevia leaves, composing approximately 10%-20% of the total dry weight. On a dry weight basis, the four major glycosides found in the leaves of Stevia typically include stevioside (9.1%), rebaudioside A (3.8%), rebaudioside C (0.6-1.0%) and dulcoside A (0.3%).

Morita et al. 2011 (U.S. Ser. No. 13/122,232) and Ohta et al 2010 (Ohta M., Sasa S., Inoue A., Tamai T., Fujita I, Morita K., and Matsuura F. (2010) Characterization of novel steviol glycosides from leaves of Stevia rebaudiana Morita, J. Appl. Glycosci. 57, 199-209) describe that rebaudiosides D, E, M, N and O are found in trace concentrations in the leaves of certain Stevia rebaudiana Bertoni cultivars. Due to this the purification of those glycosides, particularly rebaudiosides D, E, M, N and O can be achieved only by utilizing complex purification techniques such as chromatography, crystallization etc.

It is generally perceived that the aqueous extracts of Stevia rebaudiana are not suitable for use in food and beverage applications without further treatment such as crystallization, separation, isolation and purification of individual steviol glycosides. The reason for this is the low concentration of better tasting glycosides, particularly rebaudiosides D, E, M, N and O in regular, untreated extracts of Stevia rebaudiana.

Accordingly, there remains a need for new cultivars of Stevia rebaudiana containing higher concentrations of rebaudiosides D, E, M, N and O, which can enable manufacturing of stevia extracts with higher concentrations of respective glycosides and their use as sweeteners and/or flavor ingredients without further treatment such as crystallization, separation, isolation and purification of individual steviol glycosides.

SUMMARY OF THE INVENTION

The present invention relates to a process for preparing compositions comprising steviol glycosides from Stevia rebaudiana biomass. The present invention also relates to the use of compositions comprising steviol glycosides as a sweetener and/or flavor enhancer.

Hereinafter the term “steviol glycoside(s)” will mean steviol glycosides naturally occurring in Stevia rebaudiana, including but not limited to steviolmonoside, steviolbioside, rubusoside, dulcoside B, dulcoside A, rebaudioside B, rebaudioside G, stevioside, rebaudioside C, rebaudioside F, rebaudioside A, rebaudioside I, rebaudioside E, rebaudioside H, rebaudioside L, rebaudioside K, rebaudioside J, rebaudioside M, rebaudioside D, rebaudioside N, rebaudioside O, and combinations thereof.

Hereinafter the terms “RebA”, “RebB”, “RebC”, “RebD”, “RebE”, “RebF”, “RebM”, “RebN”, and “RebO” refer to Rebaudiosides A, B, C, D, E, F, M, N, and O.

Hereinafter the terms “RebD2”, “RebG”, “RebH”, “RebI”, “RebJ”, “RebK”, “RebL”, “RebM2”, “RebP”, “RebQ” “RebR”, RebS”, “RebT”, “RebU”, “RebV”, “RebW”, “RebX”, “RebY”, and “RebZ”, refer to Rebaudiosides D2, G, H, I, J, K, L, M2, P, Q, R, S, T, U, V, W, X, Y and Z.

Hereinafter the terms “Stev”, “Sbio”, “DulA”, “Rub”, refer to Stevioside, Steviolbioside, Dulcoside A and Rubusoside.

Hereinafter the term “TSG content” will mean Total Steviol Glycosides (TSG) content, and it will be calculated as the sum of the concentrations of Rebaudioside A, Rebaudioside B, Rebaudioside C, Rebaudioside D, Rebaudioside E, Rebaudioside F, Rebaudioside M, Rebaudioside N, Rebaudioside O, Stevioside, Steviolbioside, Dulcoside A and Rubusoside on a wt/wt dry basis.

Hereinafter the term “relative concentration” will mean the percent ratio of the concentration of Rebaudioside A, Rebaudioside B, Rebaudioside C, Rebaudioside D, Rebaudioside E, Rebaudioside F, Rebaudioside M, Rebaudioside N, Rebaudioside O, Stevioside, Steviolbioside, Dulcoside A, or Rubusoside (on a wt/wt dry basis) to Total Steviol Glycosides (TSG) content. For example if the composition comprises 10% RebO, 40% Stev, 0% RebA, 0% RebB, 0% RebC, 0% RebD, 0% RebE, 0% RebF, 0% RebM, 0% RebN, 0% Sbio, 0% DulA and 0% Rub (all concentration being % wt/wt on dry basis) the TSG content of the composition will be 50% (wt/wt on dry basis). Since the concentration of RebO is 10% (wt/wt on dry basis) the relative concentration of RebO will be 20% and will be calculated as follows:

Relative concentration of RebO (%)={concentration of RebO (% wt/wt on dry base)/TSG content (% wt/wt on dry basis)}100%

Similarly the relative concentrations of other glycosides can be calculated. The “common relative concentration” shall refer to the relative concentration of steviol glycosides occurring in known varieties and untreated aqueous extracts of Stevia rebaudiana plants. As used herein, “untreated aqueous extract(s)” shall refer to an extract or extracts from Stevia rebaudiana plants that has or have not been subjected to techniques used to purify, isolate or further concentrate a certain steviol glycoside, or a group of steviol glycosides, from the extract.

Hereinafter the term “relative ratio” will mean the ratio of the concentration of one steviol glycoside to another. For example if the composition comprises 10% RebO, 40% Stev, 0% RebA, 0% RebB, 0% RebC, 0% RebD, 0% RebE, 0% RebF, 0% RebM, 0% RebN, 0% Sbio, 0% DulA and 0% Rub (all concentration being % wt/wt on dry basis) the relative ratio of RebO to Stevioside will be 0.25 and will be calculated as follows:

Relative ratio of RebO to Stev=concentration of RebO (% wt/wt on dry basis)/concentration of Stev (% wt/wt on dry basis)

In the invention, Stevia rebaudiana plant biomass, particularly the dry leaves, were used as a starting material. Optionally the leaves may be not dried as well. The leaves may be optionally ground into fine powder. However not only the leaves but also the other parts of the Stevia rebaudiana plant such as stems, roots, flowers etc. or combinations thereof may be used as starting material.

The process for preparing steviol glycosides compositions may comprise the steps of:

a) providing Stevia rebaudiana leaves, wherein Stevia rebaudiana leaves comprise at least one steviol glycoside selected from the group consisting of RebE, RebM, RebD, RebN, and RebO, wherein the steviol glycoside is present above common relative concentration,

b) providing solvent;

c) contacting the Stevia rebaudiana leaves with solvent to extract the steviol glycosides from the leaves;

d) separating the Stevia rebaudiana leaves to obtain Stevia extract solution comprising at least one steviol glycoside selected from the group consisting of RebE, RebM, RebD, RebN, and RebO, wherein the steviol glycoside is present above common relative concentration, HSG-Extract.

The solvent may be water, alcohol, aqueous alcohol, or any other solvent known to be used in production of stevia extracts or plant extracts.

The process may further include other refining and purification techniques or processes known to be used in production of steviol glycosides. Non limiting examples include, flocculation, ion-exchange resin treatment, membrane filtration, macroporous adsorption resin treatment, activated carbon treatment, chromatographic separation, crystallization, centrifugation, blending, drying, milling, sieving, granulation, agglomeration, solubilisation, in any order or step numbers.

The present invention provides stevia compositions called “HSG Extracts” comprising at least one of the steviol glycosides selected from the group including Rebaudioside E, Rebaudioside D, Rebaudioside M, Rebaudioside N, Rebaudioside O, or combinations thereof, wherein the at least one of the steviol glycosides selected from the group including RebE, RebD, RebM, RebN, RebO, is present in a relative concentration higher than the common relative concentration occurring in known varieties and/or untreated aqueous extracts of Stevia rebaudiana plant.

DETAILED DESCRIPTION

The present invention relates to a process for preparing compositions comprising steviol glycosides from Stevia rebaudiana biomass. The present invention also relates to the use of compositions comprising steviol glycosides as a sweetener and/or flavor enhancer.

The present invention provides new cultivars of Stevia rebaudiana plant, comprising at least one of the steviol glycosides selected from the group including Rebaudioside E, Rebaudioside D, Rebaudioside M, Rebaudioside N, Rebaudioside O, or combinations thereof, wherein the at least one of the steviol glycosides selected from the group including RebE, RebD, RebM, RebN, RebO, is present in a relative concentration higher than the common relative concentration occurring in known varieties and untreated aqueous extracts of Stevia rebaudiana plant.

In one embodiment the dried leaves of at least one Stevia rebaudiana cultivar selected from group 814011, 807086, 817096 are subjected to aqueous extraction (e.g. according to procedure described in U.S. Ser. No. 13/122,232) to prepare stevia compositions called “HSG-Extracts”.

Any other extraction method can be used as well.

The present invention provides stevia compositions called “HSG-Extracts” comprising at least one steviol glycoside selected from the group consisting of RebE, RebM, RebD, RebN, and RebO, wherein the steviol glycoside is present above common relative concentration occurring in known varieties and untreated aqueous extracts of Stevia rebaudiana plant, and wherein for RebE this common relative concentration is 1.0%, for RebM 1.4%, for RebD 2.4%, for RebN 1.6%, and for RebO 0.8%.

Optionally, the method of the present invention further comprises purifying RebE, RebM, RebD, RebN, and RebO from the HSG-Extract. Any suitable purification method can be used, such as, for example, crystallization, separation by membranes, centrifugation, extraction (liquid or solid phase), chromatographic separation, HPLC (preparative or analytical) or a combination of such methods.

In one embodiment, the HSG-Extract is provided as part of a mixture. In a particular embodiment, the mixture is selected from the group consisting of a mixture of steviol glycosides, a Stevia extract, by-products of other steviol glycosides' isolation and purification processes, or any combination thereof. In one embodiment, the mixture contains HSG-Extract in an amount that ranges from about 10% to about 99% by weight on a dry basis, such as, for example, from about 20% to about 99%, from about 30% to about 99%, from about 40% to about 99%, from about 50% to about 99%, from about 60% to about 99%, from about 70% to about 99%, from about 80% to about 99% and from about 90% to about 99%. In a particular embodiment, the mixture contains HSG-Extract in an amount greater than about 90% by weight on a dry basis, for example, greater than about 91%, greater than about 92%, greater than about 93%, greater than about 94%, greater than about 95%, greater than about 96%, greater than about 97%, greater than about 98% and greater than about 99%.

In one embodiment the HSG-extract contains one or more additional steviol glycosides including, but not limited to, naturally occurring steviol glycosides, e.g. steviolmonoside, steviolbioside, rubusoside, dulcoside B, dulcoside A, rebaudioside B, rebaudioside G, stevioside, rebaudioside C, rebaudioside F, rebaudioside A, rebaudioside I, rebaudioside E, rebaudioside H, rebaudioside L, rebaudioside K, rebaudioside J, rebaudioside M, rebaudioside M2, rebaudioside D, rebaudioside D2, rebaudioside N, rebaudioside O, synthetic steviol glycosides, e.g. enzymatically glucosylated steviol glycosides and combinations thereof.

HSG-Extract can be present in the composition in an amount effective to provide a concentration from about 1 ppm to about 10,000 ppm when the composition is added to a consumable, such as, for example, from about 1 ppm to about 4,000 ppm, from about 1 ppm to about 3,000 ppm, from about 1 ppm to about 2,000 ppm, from about 1 ppm to about 1,000 ppm. In another embodiment, a HSG-Extract is present in the composition in an amount effective to provide a concentration from about 10 ppm to about 1,000 ppm when the composition is added to a consumable, such as, for example, from about 10 ppm to about 800 ppm, from about 50 ppm to about 800 ppm, from about 50 ppm to about 600 ppm or from about 200 ppm to about 250 ppm. In a particular embodiment, HSG-Extract is present in the composition in an amount effective to provide a concentration from about 300 ppm to about 600 ppm when the composition is added to a consumable.

Sweetener Compositions

In one embodiment, the present invention is a sweetener composition comprising HSG-Extract.

“Sweetener composition,” as used herein, refers to a composition useful to sweeten a sweetenable composition (i.e. a composition that can be sweetened) that contains at least one sweet component in combination with at least one other substance.

In one embodiment, HSG-Extract is the sole sweetener in the sweetener composition, i.e. HSG-Extract is the only compound present in the sweetener composition that provides a detectable sweetness. In another embodiment, the sweetener composition includes a compound of HSG-Extract in combination with one or more sweetener compounds.

The amount of HSG-Extract in the sweetener composition may vary. In one embodiment, HSG-Extract is present in a sweetener composition in any amount to impart the desired sweetness when the sweetener composition is added to a sweetenable composition or sweetenable consumable.

The sweetness of a non-sucrose sweetener can also be measured against a sucrose reference by determining the non-sucrose sweetener's sucrose equivalence. Typically, taste panelists are trained to detect sweetness of reference sucrose solutions containing between 1-15% sucrose (w/v). Other non-sucrose sweeteners are then tasted at a series of dilutions to determine the concentration of the non-sucrose sweetener that is as sweet as a given percent sucrose reference. For example, if a 1% solution of a sweetener is as sweet as a 10% sucrose solution, then the sweetener is said to be 10 times as potent as sucrose.

In one embodiment, HSG-Extract is present in the sweetener composition in an amount effective to provide a sucrose equivalence of greater than about 10% (w/v) when the sweetener composition is added to a sweetenable composition or sweetenable consumable, such as, for example, greater than about 11%, greater than about 12%, greater than about 13% or greater than about 14%.

The amount of sucrose, and thus another measure of sweetness, in a reference solution may be described in degrees Brix (° Bx). One degree Brix is 1 gram of sucrose in 100 grams of solution and represents the strength of the solution as percentage by weight (% w/w) (strictly speaking, by mass). In one embodiment, a sweetener composition comprises HSG-Extract in an amount effective to provide sweetness equivalent from about 0.50 to 14 degrees Brix of sugar when present in a sweetened composition, such as, for example, from about 5 to about 11 degrees Brix, from about 4 to about 7 degrees Brix, or about 5 degrees Brix. In yet another embodiment a composition comprising HSG-Extract is present with at least one other sweetener in an amount effective to provide any one of the sweetness equivalents listed above.

In one embodiment, HSG-Extract is present in the sweetener composition in an amount effective to provide a concentration from about 1 ppm to about 10,000 ppm when the sweetener composition is added to a consumable (e.g., a beverage), such as, for example, from about 1 ppm to about 4,000 ppm, from about 1 ppm to about 3,000 ppm, from about 1 ppm to about 2,000 ppm, from about 1 ppm to about 1,000 ppm. In another embodiment, HSG-Extract is present in the sweetener composition in an amount effective to provide a concentration from about 10 ppm to about 1,000 ppm when the composition is added to a consumable, such as, for example, from about 10 ppm to about 800 ppm, from about 50 ppm to about 800 ppm, from about 50 ppm to about 600 ppm or from about 200 ppm to about 250 ppm. In a particular embodiment, HSG-Extract is present in the sweetener composition in an amount effective to provide a concentration from about 300 ppm to about 600 ppm when the sweetener composition is added to the consumable.

In some embodiments, HSG-Extract is present in the sweetener composition in an amount effective to provide a concentration of the compound that is above, at or below its threshold sweetener recognition level when the sweetener composition is added to a consumable (e.g., a beverage).

Flavor Enhancing Compositions

In one aspect, the present invention is a flavor enhancing composition comprising HSG-Extract.

“Flavor enhancer compositions,” as used herein, refers to a composition capable of enhancing or intensifying the perception of a particular flavor in a consumable. The terms “flavor enhancing compositions” or “flavor enhancer” are synonymous with the terms “flavor potentiator,” “flavor amplifier,” and “flavor intensifier.” Generally, the flavor enhancing composition provided herein may enhance or potentiate the taste of flavor ingredients, i.e. any substance that provides sweetness, sourness, saltiness, savoriness, bitterness, metallic taste, astringency, sweet lingering aftertaste, sweetness onset, etc. Without being bound by any theory, the flavor enhancing composition likely does not contribute any noticeable taste to the consumable to which it is added because HSG-Extract is present in the consumable in a concentration at or below its flavor recognition threshold concentration.

“Flavor recognition threshold concentration,” as used herein, refers to the lowest concentration at which the particular flavor or off-taste of a component (e.g., a compound) is perceptible in a consumable. The flavor recognition threshold concentration varies for different compounds, and may be varied with respect to the individual perceiving the flavor or the particular consumable.

In one embodiment, the flavor enhancing composition comprises HSG-Extract in an amount effective to provide a concentration that is at or below the threshold flavor recognition concentration of HSG-Extract when the flavor enhancing composition is added to a consumable.

In a particular embodiment, HSG-Extract is present in the flavor-enhancing composition in an amount effective to provide a concentration that is below the threshold flavor recognition concentration of HSG-Extract when the flavor enhancing composition is added to a consumable.

In certain embodiment, HSG-Extract is present in the flavor enhancing composition in an amount effective to provide a concentration that is at least about 1%, at least about 5%, at least about 10%, at least about 15%, at least about 20%, at least about 25%, at least about 30%, at least about 35%, at least about 40%, at least about 45% or at least about 50% or more below the threshold flavor recognition concentration when the flavor enhancing composition is added to a consumable.

In some embodiments, HSG-Extract is present in the flavor enhancing composition in an amount that, when added to the consumable, will provide a concentration of ranging from about 0.5 ppm to about 1000 ppm. For example, HSG-Extract is present in the composition in an amount that, when added to the consumable, will provide a concentration ranging from about 1 ppm to about 300 ppm, from about 0.1 ppm to about 75 ppm, or from about 500 ppm to about 3,000 ppm.

A person of skill in the art will be able to select the concentration of HSG-Extract in the flavor enhancing composition so that it may impart an enhanced flavor to a consumable comprising at least one flavor ingredient. For example, a skilled artisan may select a concentration for HSG-Extract in the flavor enhancing composition so that the flavor enhancing composition and/or the HSG-Extract does not impart any perceptible flavor to a consumable when the flavor enhancing composition is added thereto.

In one embodiment, addition of the flavor enhancing composition increases the detected flavor of the at least one flavor ingredient in the consumable compared to the detected flavor of the same ingredient in the consumable in the absence of the flavor enhancer.

Suitable flavor ingredients include, but are not limited to, vanillin, vanilla extract, mango extract, cinnamon, citrus, coconut, ginger, viridiflorol, almond, menthol (including menthol without mint), grape skin extract, and grape seed extract. “Flavorant” and “flavoring ingredient” are synonymous and can include natural or synthetic substances or combinations thereof. Flavorants also include any other substance which imparts flavor and may include natural or non-natural (synthetic) substances which are safe for human or animals when used in a generally accepted range. Non-limiting examples of proprietary flavorants include Döhler™ Natural Flavoring Sweetness Enhancer K14323 (Döhler™, Darmstadt, Germany), Symrise™ Natural Flavor Mask for Sweeteners 161453 and 164126 (Symrise™, Holzminden, Germany), Natural Advantage™ Bitterness Blockers 1, 2, 9 and 10 (Natural Advantage™, Freehold, N.J., U.S.A.), and Sucramask™ (Creative Research Management, Stockton, Calif., U.S.A.).

In another embodiment, the flavor enhancer composition comprising HSG-Extract enhances flavors (either individual flavors or the overall flavor) when added to the consumable. Alternatively, HSG-Extract may be added directly to the consumable, i.e., not provided in the form of a composition, to enhance flavor. In this embodiment, HSG-Extract is a flavor enhancer and it is added to the consumable at a concentration at or below its threshold flavor recognition concentration.

In a particular embodiment, the flavor enhancing composition is a sweetness enhancing composition. “Sweetness enhancing composition,” as used herein, refers to a composition capable of enhancing or intensifying the perception of sweet taste of a consumable, such as a beverage. The term “sweetness enhancer” is synonymous with the terms “sweet taste potentiator,” “sweetness potentiator,” “sweetness amplifier,” and “sweetness intensifier.”

“Sweetness recognition threshold concentration,” as used herein, is the lowest known concentration of a sweet compound that is perceivable by the human sense of taste. Generally, the sweetness enhancing composition of the present invention may enhance or potentiate the sweet taste of a consumable without providing any noticeable sweet taste itself because the concentration of HSG-Extract in the sweetness enhancing composition is at or below its sweetness recognition threshold concentration, either in the sweetness enhancing compositions, the consumable after the sweetness enhancing composition has been added, or both. The sweetness recognition threshold concentration is specific for a particular compound, and can vary based on temperature, matrix, ingredients and/or flavor system.

In one embodiment, a sweetness enhancing composition comprises HSG-Extract in an amount effective to provide a concentration that is at or below the threshold sweetness recognition concentration of HSG-Extract when the sweetness enhancing composition is added to a consumable.

In a particular embodiment, a sweetness enhancing composition comprises HSG-Extract in an amount effective to provide a concentration that is below the threshold sweetness recognition concentration of HSG-Extract when the sweetness enhancing composition is added to a consumable.

In certain embodiments, HSG-Extract is present in the sweetness enhancing composition in an amount effective to provide a concentration that is at least about 1%, at least about 5%, at least about 10%, at least about 15%, at least about 20%, at least about 25%, at least about 30%, at least about 35%, at least about 40%, at least about 45% or at least about 50% or more below the threshold sweetness recognition concentration of HSG-Extract when the sweetness enhancing composition is added to a consumable.

In some embodiments, HSG-Extract is present in the sweetness enhancing composition in an amount that, when added to the consumable, will provide a concentration of the compound of HSG-Extract ranging from about 0.5 ppm to about 1000 ppm. For example, HSG-Extract is present in the composition in an amount that, when added to the consumable, will provide a concentration ranging from about 1 ppm to about 300 ppm, from about 0.1 ppm to about 75 ppm, or from about 500 ppm to about 3,000 ppm. Alternatively, HSG-Extract may be added directly to the consumable, i.e., not provided in the form of a composition, to enhance sweetness. In this embodiment, HSG-Extract is a sweetness enhancer and it is added to the consumable at a concentration at or below its sweetness recognition threshold concentration.

The sweetness of a given composition is typically measured with reference to a solution of sucrose. See generally “A Systematic Study of Concentration-Response Relationships of Sweeteners,” G. E. DuBois, D. E. Walters, S. S. Schiffman, Z. S. Warwick, B. J. Booth, S. D. Pecore, K. Gibes, B. T. Carr, and L. M. Brands, in Sweeteners: Discovery, Molecular Design and Chemoreception, D. E. Walters, F. T. Orthoefer, and G. E. DuBois, Eds., American Chemical Society, Washington, D.C. (1991), pp 261-276.

It is contemplated that the sweetness enhancing composition can include one or more sweetness enhancers in addition to HSG-Extract. In one embodiment, the sweetness enhancing composition can include one additional sweetness enhancer. In other embodiments, the sweetness enhancing composition can include two or more additional sweetness enhancers.

In one embodiment, the sweetener is a caloric sweetener or mixture of caloric sweeteners. In another embodiment, the caloric sweetener is selected from sucrose, fructose, glucose, high fructose corn/starch syrup, a beet sugar, a cane sugar, and combinations thereof.

In another embodiment, the sweetener is a rare sugar selected from D-psicose, D-allose, L-ribose, D-tagatose, L-glucose, L-fucose, L-arbinose, turanose and combinations thereof.

In yet another embodiment, the sweetener is a non-caloric sweetener or mixture of non-caloric sweeteners. In one example, the non-caloric sweetener is a natural high-potency sweetener. As used herein, the phrase “natural high potency sweetener” refers to any composition which is not found naturally in nature and characteristically has a sweetness potency greater than sucrose, fructose, or glucose, yet has less calories. The natural high potency sweetener can be provided as a pure compound or, alternatively, as part of an extract.

In yet another example, the non-caloric sweetener is a synthetic high-potency sweetener. As used herein, the phrase “synthetic sweetener” refers to any composition which is not found naturally in nature and characteristically has a sweetness potency greater than sucrose, fructose, or glucose, yet has less calories.

In one embodiment, addition of the sweetness enhancer increases the detected sucrose equivalence of the at least one sweetener in a consumable compared to the sucrose equivalence of the same consumable in the absence of the sweetness enhancer.

In a particular embodiment, the consumable is a beverage. The beverage comprises HSG-Extract and at least one sweetener, wherein HSG-Extract is present in a concentration at or below its sweetness recognition threshold. The HSG-Extract and at least one sweetener can each be provided separately, or provided in the form of a sweetness enhancing composition. In a particular embodiment, the detected sucrose equivalence is increased from, for example, about 0.2% to about 5.0%, such as, for example, about 1%, about 2%, about 3%, about 4% or about 5%.

The sweetener can be any natural or synthetic sweetener provided herein. In a particular embodiment, the sweetener is a calorie-providing carbohydrate sweetener. Accordingly, incorporation of the sweetness enhancer thereby reduces the quantity of the calorie-providing carbohydrate sweetener that must be used in a given consumable, thereby allowing the preparation of reduced-calorie consumables.

The compositions can be customized to provide the desired calorie content. For example, compositions can be “full-calorie”, such that they impart the desired sweetness when added to a consumable (such as, for example, a beverage) and have about 120 calories per 8 oz serving. Alternatively, compositions can be “mid-calorie”, such that they impart the desired sweetness when added to a consumable (such as, for example, as beverage) and have less than about 60 calories per 8 oz serving. In other embodiments, compositions can be “low-calorie”, such that they impart the desired sweetness when added to a consumable (such as, for example, as beverage) and have less than 40 calories per 8 oz serving. In still other embodiments, the compositions can be “zero-calorie”, such that they impart the desired sweetness when added to a consumable (such as, for example, a beverage) and have less than 5 calories per 8 oz. serving.

Saponin

In certain embodiments, the functional ingredient is at least one saponin. As used herein, the at least one saponin may comprise a single saponin or a plurality of saponins as a functional ingredient for the composition provided herein. Generally, according to particular embodiments of this invention, the at least one saponin is present in the composition in an amount sufficient to promote health and wellness.

Saponins are glycosidic natural plant products comprising an aglycone ring structure and one or more sugar moieties. The combination of the nonpolar aglycone and the water soluble sugar moiety gives saponins surfactant properties, which allow them to form a foam when shaken in an aqueous solution.

The saponins are grouped together based on several common properties. In particular, saponins are surfactants which display hemolytic activity and form complexes with cholesterol. Although saponins share these properties, they are structurally diverse. The types of aglycone ring structures forming the ring structure in saponins can vary greatly. Non-limiting examples of the types of aglycone ring structures in saponin for use in particular embodiments of the invention include steroids, triterpenoids, and steroidal alkaloids. Non-limiting examples of specific aglycone ring structures for use in particular embodiments of the invention include soyasapogenol A, soyasapogenol B and soyasopogenol E. The number and type of sugar moieties attached to the aglycone ring structure can also vary greatly.

Non-limiting examples of specific saponins for use in particular embodiments of the invention include group A acetyl saponin, group B acetyl saponin, and group E acetyl saponin.

Saponins can be found in a large variety of plants and plant products, and are especially prevalent in plant skins and barks where they form a waxy protective coating. Several common sources of saponins include soybeans, which have approximately 5% saponin content by dry weight, soapwort plants (Saponaria), the root of which was used historically as soap, as well as alfalfa, aloe, asparagus, grapes, chickpeas, yucca, and various other beans and weeds. Saponins may be obtained from these sources by using extraction techniques well known to those of ordinary skill in the art. A description of conventional extraction techniques can be found in U.S. Pat. Appl. No. 2005/0123662, the disclosure of which is expressly incorporated by reference.

In certain embodiments, the functional ingredient is at least one dietary fiber source. As used herein, the at least one dietary fiber source may comprise a single dietary fiber source or a plurality of dietary fiber sources as a functional ingredient for the compositions provided herein. Generally, according to particular embodiments of this invention, the at least one dietary fiber source is present in the composition in an amount sufficient to promote health and wellness.

Numerous polymeric carbohydrates having significantly different structures in both composition and linkages fall within the definition of dietary fiber. Such compounds are well known to those skilled in the art, non-limiting examples of which include non-starch polysaccharides, lignin, cellulose, methylcellulose, the hemicelluloses, β-glucans, pectins, gums, mucilage, waxes, inulins, oligosaccharides, fructooligosaccharides, cyclodextrins, chitins, and combinations thereof.

Polysaccharides are complex carbohydrates composed of monosaccharides joined by glycosidic linkages. Non-starch polysaccharides are bonded with β-linkages, which humans are unable to digest due to a lack of an enzyme to break the β-linkages. Conversely, digestible starch polysaccharides generally comprise α(1-4) linkages.

Lignin is a large, highly branched and cross-linked polymer based on oxygenated phenylpropane units. Cellulose is a linear polymer of glucose molecules joined by a β(1-4) linkage, which mammalian amylases are unable to hydrolyze. Methylcellulose is a methyl ester of cellulose that is often used in foodstuffs as a thickener, and emulsifier. It is commercially available (e.g., Citrucel by GlaxoSmithKline, Celevac by Shire Pharmaceuticals). Hemicelluloses are highly branched polymers consisting mainly of glucurono- and 4-O-methylglucuroxylans. β-Glucans are mixed-linkage (1-3), (1-4) β-D-glucose polymers found primarily in cereals, such as oats and barley. Pectins, such as beta pectin, are a group of polysaccharides composed primarily of D-galacturonic acid, which is methoxylated to variable degrees.

Gums and mucilages represent a broad array of different branched structures. Guar gum, derived from the ground endosperm of the guar seed, is a galactomannan. Guar gum is commercially available (e.g., Benefiber by Novartis AG). Other gums, such as gum arabic and pectins, have still different structures. Still other gums include xanthan gum, gellan gum, tara gum, psylium seed husk gum, and locust been gum.

Waxes are esters of ethylene glycol and two fatty acids, generally occurring as a hydrophobic liquid that is insoluble in water.

Inulins comprise naturally occurring oligosaccharides belonging to a class of carbohydrates known as fructans. They generally are comprised of fructose units joined by β(2-1) glycosidic linkages with a terminal glucose unit. Oligosaccharides are saccharide polymers containing typically three to six component sugars. They are generally found either O- or N-linked to compatible amino acid side chains in proteins or to lipid molecules. Fructooligosaccharides are oligosaccharides consisting of short chains of fructose molecules.

Food sources of dietary fiber include, but are not limited to, grains, legumes, fruits, and vegetables. Grains providing dietary fiber include, but are not limited to, oats, rye, barley, wheat. Legumes providing fiber include, but are not limited to, peas and beans such as soybeans. Fruits and vegetables providing a source of fiber include, but are not limited to, apples, oranges, pears, bananas, berries, tomatoes, green beans, broccoli, cauliflower, carrots, potatoes, celery. Plant foods such as bran, nuts, and seeds (such as flax seeds) are also sources of dietary fiber. Parts of plants providing dietary fiber include, but are not limited to, the stems, roots, leaves, seeds, pulp, and skin.

Although dietary fiber generally is derived from plant sources, indigestible animal products such as chitins are also classified as dietary fiber. Chitin is a polysaccharide composed of units of acetylglucosamine joined by β(1-4) linkages, similar to the linkages of cellulose.

Sources of dietary fiber often are divided into categories of soluble and insoluble fiber based on their solubility in water. Both soluble and insoluble fibers are found in plant foods to varying degrees depending upon the characteristics of the plant. Although insoluble in water, insoluble fiber has passive hydrophilic properties that help increase bulk, soften stools, and shorten transit time of fecal solids through the intestinal tract.

Unlike insoluble fiber, soluble fiber readily dissolves in water. Soluble fiber undergoes active metabolic processing via fermentation in the colon, increasing the colonic microflora and thereby increasing the mass of fecal solids. Fermentation of fibers by colonic bacteria also yields end-products with significant health benefits. For example, fermentation of the food masses produces gases and short-chain fatty acids. Acids produced during fermentation include butyric, acetic, propionic, and valeric acids that have various beneficial properties such as stabilizing blood glucose levels by acting on pancreatic insulin release and providing liver control by glycogen breakdown. In addition, fiber fermentation may reduce atherosclerosis by lowering cholesterol synthesis by the liver and reducing blood levels of LDL and triglycerides. The acids produced during fermentation lower colonic pH, thereby protecting the colon lining from cancer polyp formation. The lower colonic pH also increases mineral absorption, improves the barrier properties of the colonic mucosal layer, and inhibits inflammatory and adhesion irritants. Fermentation of fibers also may benefit the immune system by stimulating production of T-helper cells, antibodies, leukocytes, splenocytes, cytokinins and lymphocytes.

As used herein, the at least one probiotic or prebiotic may be single probiotic or prebiotic or a plurality of probiotics or prebiotics as a functional ingredient for the compositions provided herein. Generally, according to particular embodiments of this invention, the at least one probiotic, prebiotic or combination thereof is present in the composition in an amount sufficient to promote health and wellness.

Probiotics, in accordance with the teachings of this invention, comprise microorganisms that benefit health when consumed in an effective amount. Desirably, probiotics beneficially affect the human body's naturally-occurring gastrointestinal microflora and impart health benefits apart from nutrition. Probiotics may include, without limitation, bacteria, yeasts, and fungi.

Prebiotics, in accordance with the teachings of this invention, are compositions that promote the growth of beneficial bacteria in the intestines. Prebiotic substances can be consumed by a relevant probiotic, or otherwise assist in keeping the relevant probiotic alive or stimulate its growth. When consumed in an effective amount, prebiotics also beneficially affect the human body's naturally-occurring gastrointestinal microflora and thereby impart health benefits apart from just nutrition. Prebiotic foods enter the colon and serve as substrate for the endogenous bacteria, thereby indirectly providing the host with energy, metabolic substrates, and essential micronutrients. The body's digestion and absorption of prebiotic foods is dependent upon bacterial metabolic activity, which salvages energy for the host from nutrients that escaped digestion and absorption in the small intestine.

According to particular embodiments, the probiotic is a beneficial microorganism that beneficially affects the human body's naturally-occurring gastrointestinal microflora and imparts health benefits apart from nutrition. Examples of probiotics include, but are not limited to, bacteria of the genus Lactobacilli, Bifidobacteria, Streptococci, or combinations thereof, that confer beneficial effects to humans.

In particular embodiments of the invention, the at least one probiotic is chosen from the genus Lactobacilli. Lactobacilli (i.e., bacteria of the genus Lactobacillus, hereinafter “L.”) have been used for several hundred years as a food preservative and for promoting human health. Non-limiting examples of species of Lactobacilli found in the human intestinal tract include L. acidophilus, L. casei, L. fermentum, L. saliva roes, L. brevis, L. leichmannii, L. plantarum, L. cellobiosus, L. reuteri, L. rhamnosus, L. GG, L. bulgaricus, and L. thermophilus.

According to other particular embodiments of this invention, the probiotic is chosen from the genus Bifidobacteria. Bifidobacteria also are known to exert a beneficial influence on human health by producing short chain fatty acids (e.g., acetic, propionic, and butyric acids), lactic, and formic acids as a result of carbohydrate metabolism. Non-limiting species of Bifdobacteria found in the human gastrointestinal tract include B. angulatum, B. animalis, B. asteroides, B. bifidum, B. boum, B. breve, B. catenulatum, B. choerinum, B. coryneforme, B. cuniculi, B. dentium, B. gallicum, B. gallinarum, B indicum, B. longum, B. magnum, B. merycicum, B. minimum, B. pseudocatenulatum, B. pseudolongum, B. psychraerophilum, B. pullorum, B. ruminantium, B. saeculare, B. scardovii, B. simiae, B. subtile, B. thermacidophilum, B. thermophilum, B. urinalis, and B. sp.

According to other particular embodiments of this invention, the probiotic is chosen from the genus Streptococcus. Streptococcus thermophilus is a gram-positive facultative anaerobe. It is classified as a lactic acid bacteria and commonly is found in milk and milk products, and is used in the production of yogurt. Other non-limiting probiotic species of this bacteria include Streptococcus salivarus and Streptococcus cremoris.

Probiotics that may be used in accordance with this invention are well-known to those of skill in the art. Non-limiting examples of foodstuffs comprising probiotics include yogurt, sauerkraut, kefir, kimchi, fermented vegetables, and other foodstuffs containing a microbial element that beneficially affects the host animal by improving the intestinal microbalance.

Prebiotics, in accordance with the embodiments of this invention, include, without limitation, mucopolysaccharides, oligosaccharides, polysaccharides, amino acids, vitamins, nutrient precursors, proteins and combinations thereof.

According to a particular embodiment of this invention, the prebiotic is chosen from dietary fibers, including, without limitation, polysaccharides and oligosaccharides. These compounds have the ability to increase the number of probiotics, which leads to the benefits conferred by the probiotics. Non-limiting examples of oligosaccharides that are categorized as prebiotics in accordance with particular embodiments of this invention include fructooligosaccharides, inulins, isomalto-oligosaccharides, lactilol, lactosucrose, lactulose, pyrodextrins, soy oligosaccharides, transgalacto-oligosaccharides, and xylo-oligosaccharides.

According to other particular embodiments of the invention, the prebiotic is an amino acid. Although a number of known prebiotics break down to provide carbohydrates for probiotics, some probiotics also require amino acids for nourishment.

Prebiotics are found naturally in a variety of foods including, without limitation, bananas, berries, asparagus, garlic, wheat, oats, barley (and other whole grains), flaxseed, tomatoes, Jerusalem artichoke, onions and chicory, greens (e.g., dandelion greens, spinach, collard greens, chard, kale, mustard greens, turnip greens), and legumes (e.g., lentils, kidney beans, chickpeas, navy beans, white beans, black beans).

Weight Management Agent

In certain embodiments, the functional ingredient is at least one weight management agent.

As used herein, the at least one weight management agent may be single weight management agent or a plurality of weight management agents as a functional ingredient for the compositions provided herein. Generally, according to particular embodiments of this invention, the at least one weight management agent is present in the composition in an amount sufficient to promote health and wellness.

As used herein, “a weight management agent” includes an appetite suppressant and/or a thermogenesis agent. As used herein, the phrases “appetite suppressant”, “appetite satiation compositions”, “satiety agents”, and “satiety ingredients” are synonymous. The phrase “appetite suppressant” describes macronutrients, herbal extracts, exogenous hormones, anorectics, anorexigenics, pharmaceutical drugs, and combinations thereof, that when delivered in an effective amount, suppress, inhibit, reduce, or otherwise curtail a person's appetite. The phrase “thermogenesis agent” describes macronutrients, herbal extracts, exogenous hormones, anorectics, anorexigenics, pharmaceutical drugs, and combinations thereof, that when delivered in an effective amount, activate or otherwise enhance a person's thermogenesis or metabolism.

Suitable weight management agents include macronutrient selected from the group consisting of proteins, carbohydrates, dietary fats, and combinations thereof. Consumption of proteins, carbohydrates, and dietary fats stimulates the release of peptides with appetite-suppressing effects. For example, consumption of proteins and dietary fats stimulates the release of the gut hormone cholecytokinin (CCK), while consumption of carbohydrates and dietary fats stimulates release of Glucagon-like peptide 1 (GLP-1).

Suitable macronutrient weight management agents also include carbohydrates. Carbohydrates generally comprise sugars, starches, cellulose and gums that the body converts into glucose for energy. Carbohydrates often are classified into two categories, digestible carbohydrates (e.g., monosaccharides, disaccharides, and starch) and non-digestible carbohydrates (e.g., dietary fiber). Studies have shown that non-digestible carbohydrates and complex polymeric carbohydrates having reduced absorption and digestibility in the small intestine stimulate physiologic responses that inhibit food intake. Accordingly, the carbohydrates embodied herein desirably comprise non-digestible carbohydrates or carbohydrates with reduced digestibility. Non-limiting examples of such carbohydrates include polydextrose; inulin; monosaccharide-derived polyols such as erythritol, mannitol, xylitol, and sorbitol; disaccharide-derived alcohols such as isomalt, lactitol, and maltitol; and hydrogenated starch hydrolysates. Carbohydrates are described in more detail herein below.

In another particular embodiment weight management agent is a dietary fat. Dietary fats are lipids comprising combinations of saturated and unsaturated fatty acids. Polyunsaturated fatty acids have been shown to have a greater satiating power than mono-unsaturated fatty acids. Accordingly, the dietary fats embodied herein desirably comprise poly-unsaturated fatty acids, non-limiting examples of which include triacylglycerols.

In a particular embodiment, the weight management agents is an herbal extract. Extracts from numerous types of plants have been identified as possessing appetite suppressant properties. Non-limiting examples of plants whose extracts have appetite suppressant properties include plants of the genus Hoodia, Trichocaulon, Caralluma, Stapelia, Orbea, Asclepias, and Camelia. Other embodiments include extracts derived from Gymnema Sylvestre, Kola Nut, Citrus Auran tium, Yerba Mate, Griffonia Simplicifolia, Guarana, myrrh, guggul Lipid, and black current seed oil.

The herbal extracts may be prepared from any type of plant material or plant biomass. Non-limiting examples of plant material and biomass include the stems, roots, leaves, dried powder obtained from the plant material, and sap or dried sap. The herbal extracts generally are prepared by extracting sap from the plant and then spray-drying the sap. Alternatively, solvent extraction procedures may be employed. Following the initial extraction, it may be desirable to further fractionate the initial extract (e.g., by column chromatography) in order to obtain an herbal extract with enhanced activity. Such techniques are well known to those of ordinary skill in the art.

In a particular embodiment, the herbal extract is derived from a plant of the genus Hoodia, species of which include H. alstonii, H. currorii, H. dregei, H. flava, H. gordonii, H. jutatae, H. mossamedensis, H. oficinalis, H. parviflorai, H. pedicellata, H. pilifera, H. ruschii, and H. triebneri. Hoodia plants are stem succulents native to southern Africa. A sterol glycoside of Hoodia, known as P57, is believed to be responsible for the appetite-suppressant effect of the Hoodia species.

Arabica, and C. lasiantha. Carralluma plants belong to the same Subfamily as Hoodia, Asclepiadaceae. Caralluma are small, erect and fleshy plants native to India having medicinal properties, such as appetite suppression, that generally are attributed to glycosides belonging to the pregnane group of glycosides, non-limiting examples of which include caratuberside A, caratuberside B, bouceroside I, bouceroside II, bouceroside III, bouceroside IV, bouceroside V, bouceroside VI, bouceroside VII, bouceroside VIII, bouceroside IX, and bouceroside X.

In another particular embodiment, the at least one herbal extract is derived from a plant of the genus Trichocaulon. Trichocaulon plants are succulents that generally are native to southern Africa, similar to Hoodia, and include the species T. piliferum and T. officinale.

In another particular embodiment, the herbal extract is derived from a plant of the genus Stapelia or Orbea, species of which include S. gigantean and O. variegate, respectively. Both Stapelia and Orbea plants belong to the same Subfamily as Hoodia, Asclepiadaceae. Not wishing to be bound by any theory, it is believed that the compounds exhibiting appetite suppressant activity are saponins, such as pregnane glycosides, which include stavarosides A, B, C, D, E, F, G, H, I, J, and K.

In another particular embodiment, the herbal extract is derived from a plant of the genus Asclepias. Asclepias plants also belong to the Asclepiadaceae family of plants. Non-limiting examples of Asclepias plants include A. incarnate, A. curassayica, A. syriaca, and A. tuberose.

Long-Chain Primary Aliphatic Saturated Alcohol

In certain embodiments, the functional ingredient is at least one long chain primary aliphatic saturated alcohol.

As used herein, the at least one long chain primary aliphatic saturated alcohol may be single long chain primary aliphatic saturated alcohol or a plurality of long chain primary aliphatic saturated alcohols as a functional ingredient for the compositions provided herein. Generally, according to particular embodiments of this invention, the at least one long chain primary aliphatic saturated alcohol is present in the composition in an amount sufficient to promote health and wellness.

Long-chain primary aliphatic saturated alcohols are a diverse group of organic compounds. The term alcohol refers to the fact these compounds feature a hydroxyl group (—OH) bound to a carbon atom. The term primary refers to the fact that in these compounds the carbon atom which is bound to the hydroxyl group is bound to only one other carbon atom. The term saturated refers to the fact that these compounds feature no carbon to carbon pi bonds. The term aliphatic refers to the fact that the carbon atoms in these compounds are joined together in straight or branched chains rather than in rings. The term long-chain refers to the fact that the number of carbon atoms in these compounds is at least 8 carbons).

Non-limiting examples of particular long-chain primary aliphatic saturated alcohols for use in particular embodiments of the invention include the 8 carbon atom 1-octanol, the 9 carbon 1-nonanol, the 10 carbon atom 1-decanol, the 12 carbon atom 1-dodecanol, the 14 carbon atom 1-tetradecanol, the 16 carbon atom 1-hexadecanol, the 18 carbon atom 1-octadecanol, the 20 carbon atom 1-eicosanol, the 22 carbon 1-docosanol, the 24 carbon 1-tetracosanol, the 26 carbon 1-hexacosanol, the 27 carbon 1-heptacosanol, the 28 carbon 1-octanosol, the 29 carbon 1-nonacosanol, the 30 carbon 1-triacontanol, the 32 carbon 1-dotriacontanol, and the 34 carbon 1-tetracontanol.

In a particularly desirable embodiment of the invention, the long-chain primary aliphatic saturated alcohols are policosanol. Policosanol is the term for a mixture of long-chain primary aliphatic saturated alcohols composed primarily of 28 carbon 1-octanosol and 30 carbon 1-triacontanol, as well as other alcohols in lower concentrations such as 22 carbon 1-docosanol, 24 carbon 1-tetracosanol, 26 carbon 1-hexacosanol, 27 carbon 1-heptacosanol, 29 carbon 1-nonacosanol, 32 carbon 1-dotriacontanol, and 34 carbon 1-tetracontanol.

Long-chain primary aliphatic saturated alcohols are derived from natural fats and oils. They may be obtained from these sources by using extraction techniques well known to those of ordinary skill in the art. Policosanols can be isolated from a variety of plants and materials including sugar cane (Saccharum officinarium), yams (e.g. Dioscorea opposite), bran from rice (e.g. Oryza sativa), and beeswax. Policosanols may be obtained from these sources by using extraction techniques well known to those of ordinary skill in the art. A description of such extraction techniques can be found in U.S. Pat. Appl. No. 2005/0220868, the disclosure of which is expressly incorporated by reference.

Phytosterols

In certain embodiments, the functional ingredient is at least one phytosterol, phytostanol or combination thereof.

Generally, according to particular embodiments of this invention, the at least one phytosterol, phytostanol or combination thereof is present in the composition in an amount sufficient to promote health and wellness.

As used herein, the phrases “stanol”, “plant stanol” and “phytostanol” are synonymous.

Plant sterols and stanols are present naturally in small quantities in many fruits, vegetables, nuts, seeds, cereals, legumes, vegetable oils, bark of the trees and other plant sources. Although people normally consume plant sterols and stanols every day, the amounts consumed are insufficient to have significant cholesterol-lowering effects or other health benefits. Accordingly, it would be desirable to supplement food and beverages with plant sterols and stanols.

Sterols are a subgroup of steroids with a hydroxyl group at C-3. Generally, phytosterols have a double bond within the steroid nucleus, like cholesterol; however, phytosterols also may comprise a substituted sidechain (R) at C-24, such as an ethyl or methyl group, or an additional double bond. The structures of phytosterols are well known to those of skill in the art.

At least 44 naturally-occurring phytosterols have been discovered, and generally are derived from plants, such as corn, soy, wheat, and wood oils; however, they also may be produced synthetically to form compositions identical to those in nature or having properties similar to those of naturally-occurring phytosterols. According to particular embodiments of this invention, non-limiting examples of phytosterols well known to those or ordinary skill in the art include 4-desmethylsterols (e.g., β-sitosterol, campesterol, stigmasterol, brassicasterol, 22-dehydrobrassicasterol, and Δ5-avenasterol), 4-monomethyl sterols, and 4,4-dimethyl sterols (triterpene alcohols) (e.g., cycloartenol, 24-methylenecycloartanol, and cyclobranol).

As used herein, the phrases “stanol”, “plant stanol” and “phytostanol” are synonymous. Phytostanols are saturated sterol alcohols present in only trace amounts in nature and also may be synthetically produced, such as by hydrogenation of phytosterols. According to particular embodiments of this invention, non-limiting examples of phytostanols include β-sitostanol, campestanol, cycloartanol, and saturated forms of other triterpene alcohols.

Both phytosterols and phytostanols, as used herein, include the various isomers such as the α and β isomers (e.g., α-sitosterol and β-sitostanol, which comprise one of the most effective phytosterols and phytostanols, respectively, for lowering serum cholesterol in mammals).

The phytosterols and phytostanols of the present invention also may be in their ester form. Suitable methods for deriving the esters of phytosterols and phytostanols are well known to those of ordinary skill in the art, and are disclosed in U.S. Pat. Nos. 6,589,588, 6,635,774, 6,800,317, and U.S. Patent Publication Number 2003/0045473, the disclosures of which are incorporated herein by reference in their entirety. Non-limiting examples of suitable phytosterol and phytostanol esters include sitosterol acetate, sitosterol oleate, stigmasterol oleate, and their corresponding phytostanol esters. The phytosterols and phytostanols of the present invention also may include their derivatives.

Chewing Gum Compositions

In one embodiment, the present invention is a chewing gum composition that comprises HSG-Extract. In another embodiment, the present invention is a chewing gum composition that comprises a composition comprising HSG-Extract. Chewing gum compositions generally comprise a water-soluble portion and a water-insoluble chewable gum base portion. The water soluble portion, which typically includes the composition of the present invention, dissipates with a portion of the flavoring agent over a period of time during chewing while the insoluble gum base portion is retained in the mouth. The insoluble gum base generally determines whether a gum is considered chewing gum, bubble gum, or a functional gum.

The insoluble gum base, which is generally present in the chewing gum composition in an amount in the range of about 15 to about 35 weight percent of the chewing gum composition, generally comprises combinations of elastomers, softeners (plasticizers), emulsifiers, resins, and fillers. Such components generally are considered food grade, recognized as safe (GRA), and/or are U.S. Food and Drug Administration (FDA)-approved.

Elastomers, the primary component of the gum base, provide the rubbery, cohesive nature to gums and can include one or more natural rubbers (e.g., smoked latex, liquid latex, or guayule); natural gums (e.g., jelutong, perillo, sorva, massaranduba balata, massaranduba chocolate, nispero, rosindinha, chicle, and gutta hang kang); or synthetic elastomers (e.g., butadiene-styrene copolymers, isobutylene-isoprene copolymers, polybutadiene, polyisobutylene, and vinyl polymeric elastomers). In a particular embodiment, the elastomer is present in the gum base in an amount in the range of about 3 to about 50 weight percent of the gum base.

Resins are used to vary the firmness of the gum base and aid in softening the elastomer component of the gum base. Non-limiting examples of suitable resins include a rosin ester, a terpene resin (e.g., a terpene resin from α-pinene, β-pinene and/or d-limonene), polyvinyl acetate, polyvinyl alcohol, ethylene vinyl acetate, and vinyl acetate-vinyl laurate copolymers.

Generally, softeners comprise oils, fats, waxes, and emulsifiers. Non-limiting examples of oils and fats include tallow, hydrogenated tallow, large, hydrogenated or partially hydrogenated vegetable oils (e.g., soybean, canola, cottonseed, sunflower, palm, coconut, corn, safflower, or palm kernel oils), cocoa butter, glycerol monostearate, glycerol triacetate, glycerol abietate, leithin, monoglycerides, diglycerides, triglycerides acetylated monoglycerides, and free fatty acids. Non-limiting examples of waxes include polypropylene/polyethylene/Fisher-Tropsch waxes, paraffin, and microcrystalline and natural waxes (e.g., candelilla, beeswax and carnauba). Microcrystalline waxes, especially those with a high degree of crystallinity and a high melting point, also may be considered as bodying agents or textural modifiers. In a particular embodiment, the softeners are present in the gum base in an amount in the range of about 0.5 to about 25 weight percent of the gum base.

Emulsifiers are used to form a uniform dispersion of the insoluble and soluble phases of the chewing gum composition and also have plasticizing properties. Suitable emulsifiers include glycerol monostearate (GMS), lecithin (Phosphatidyl choline), polyglycerol polyricinoleic acid (PPGR), mono and diglycerides of fatty acids, glycerol distearate, tracetin, acetylated monoglyceride, glycerol triactetate, and magnesium stearate. In a particular embodiment, the emulsifiers are present in the gum base in an amount in the range of about 2 to about 30 weight percent of the gum base.

The chewing gum composition also may comprise adjuvants or fillers in either the gum base and/or the soluble portion of the chewing gum composition. Suitable adjuvants and fillers include lecithin, inulin, polydextrin, calcium carbonate, magnesium carbonate, magnesium silicate, ground limestome, aluminum hydroxide, aluminum silicate, talc, clay, alumina, titanium dioxide, and calcium phosphate. In particular embodiments, lecithin can be used as an inert filler to decrease the stickiness of the chewing gum composition. In other particular embodiments, lactic acid copolymers, proteins (e.g., gluten and/or zein) and/or guar can be used to create a gum that is more readily biodegradable. The adjuvants or fillers are generally present in the gum base in an amount up to about 20 weight percent of the gum base. Other optional ingredients include coloring agents, whiteners, preservatives, and flavors.

In particular embodiments of the chewing gum composition, the gum base comprises about 5 to about 95 weight percent of the chewing gum composition, more desirably about 15 to about 50 weight percent of the chewing gum composition, and even more desirably from about 20 to about 30 weight percent of the chewing gum composition.

Dairy Products

In one embodiment, the consumable of the present invention is a dairy product that comprises HSG-Extract. In another embodiment, the consumable of the present invention is a dairy product that comprises a composition comprising HSG-Extract. Dairy products and processes for making dairy products suitable for use in this invention are well known to those of ordinary skill in the art. Dairy products, as used herein, comprise milk or foodstuffs produced from milk. Non-limiting examples of dairy products suitable for use in embodiments of this invention include milk, milk cream, sour cream, crème fraiche, buttermilk, cultured buttermilk, milk powder, condensed milk, evaporated milk, butter, cheese, cottage cheese, cream cheese, yogurt, ice cream, frozen custard, frozen yogurt, gelato, via, piima, filmjölk, kajmak, kephir, viili, kumiss, airag, ice milk, casein, ayran, lassi, khoa, or combinations thereof.

Milk is a fluid secreted by the mammary glands of female mammals for the nourishment of their young. The female ability to produce milk is one of the defining characteristics of mammals and provides the primary source of nutrition for newborns before they are able to digest more diverse foods. In particular embodiments of this invention, the dairy products are derived from the raw milk of cows, goats, sheep, horses, donkeys, camels, water buffalo, yaks, reindeer, moose, or humans.

In particular embodiments of this invention, the processing of the dairy product from raw milk generally comprises the steps of pasteurizing, creaming, and homogenizing. Although raw milk may be consumed without pasteurization, it usually is pasteurized to destroy harmful microorganisms such as bacteria, viruses, protozoa, molds, and yeasts. Pasteurizing generally comprises heating the milk to a high temperature for a short period of time to substantially reduce the number of microorganisms, thereby reducing the risk of disease.

Creaming traditionally follows pasteurization step, and involves the separation of milk into a higher-fat cream layer and a lower-fat milk layer. Milk will separate into milk and cream layers upon standing for twelve to twenty-four hours. The cream rises to the top of the milk layer and may be skimmed and used as a separate dairy product. Alternatively, centrifuges may be used to separate the cream from the milk. The remaining milk is classified according to the fat content of the milk, non-limiting examples of which include whole, 2%, 1%, and skim milk.

After removing the desired amount of fat from the milk by creaming, milk is often homogenized. Homogenization prevents cream from separating from the milk and generally involves pumping the milk at high pressures through narrow tubes in order to break up fat globules in the milk. Pasteurization, creaming, and homogenization of milk are common but are not required to produce consumable dairy products. Accordingly, suitable dairy products for use in embodiments of this invention may undergo no processing steps, a single processing step, or combinations of the processing steps described herein. Suitable dairy products for use in embodiments of this invention may also undergo processing steps in addition to or apart from the processing steps described herein.

Particular embodiments of this invention comprise dairy products produced from milk by additional processing steps. As described above, cream may be skimmed from the top of milk or separated from the milk using machine-centrifuges. In a particular embodiment, the dairy product comprises sour cream, a dairy product rich in fats that is obtained by fermenting cream using a bacterial culture. The bacteria produce lactic acid during fermentation, which sours and thickens the cream. In another particular embodiment, the dairy product comprises crème fraiche, a heavy cream slightly soured with bacterial culture in a similar manner to sour cream. Crème fraiche ordinarily is not as thick or as sour as sour cream. In yet another particular embodiment, the dairy product comprises cultured buttermilk. Cultured buttermilk is obtained by adding bacteria to milk. The resulting fermentation, in which the bacterial culture turns lactose into lactic acid, gives cultured buttermilk a sour taste. Although it is produced in a different manner, cultured buttermilk generally is similar to traditional buttermilk, which is a by-product of butter manufacture.

According to other particular embodiments of this invention, the dairy products comprise milk powder, condensed milk, evaporated milk, or combinations thereof. Milk powder, condensed milk, and evaporated milk generally are produced by removing water from milk. In a particular embodiment, the dairy product comprises a milk powder comprising dried milk solids with a low moisture content. In another particular embodiment, the dairy product comprises condensed milk. Condensed milk generally comprises milk with a reduced water content and added sweetener, yielding a thick, sweet product with a long shelf-life. In yet another particular embodiment, the dairy product comprises evaporated milk. Evaporated milk generally comprises fresh, homogenized milk from which about 60% of the water has been removed, that has been chilled, fortified with additives such as vitamins and stabilizers, packaged, and finally sterilized. According to another particular embodiment of this invention, the dairy product comprises a dry creamer and HSG-Extract or a composition comprising HSG-Extract.

In another particular embodiment, the dairy product provided herein comprises butter. Butter generally is made by churning fresh or fermented cream or milk. Butter generally comprises butterfat surrounding small droplets comprising mostly water and milk proteins. The churning process damages the membranes surrounding the microscopic globules of butterfat, allowing the milk fats to conjoin and to separate from the other parts of the cream. In yet another particular embodiment, the dairy product comprises buttermilk, which is the sour-tasting liquid remaining after producing butter from full-cream milk by the churning process.

In still another particular embodiment, the dairy product comprises cheese, a solid foodstuff produced by curdling milk using a combination of rennet or rennet substitutes and acidification. Rennet, a natural complex of enzymes produced in mammalian stomachs to digest milk, is used in cheese-making to curdle the milk, causing it to separate into solids known as curds and liquids known as whey. Generally, rennet is obtained from the stomachs of young ruminants, such as calves; however, alternative sources of rennet include some plants, microbial organisms, and genetically modified bacteria, fungus, or yeast. In addition, milk may be coagulated by adding acid, such as citric acid. Generally, a combination of rennet and/or acidification is used to curdle the milk. After separating the milk into curds and whey, some cheeses are made by simply draining, salting, and packaging the curds. For most cheeses, however, more processing is needed. Many different methods may be used to produce the hundreds of available varieties of cheese. Processing methods include heating the cheese, cutting it into small cubes to drain, salting, stretching, cheddaring, washing, molding, aging, and ripening. Some cheeses, such as the blue cheeses, have additional bacteria or molds introduced to them before or during aging, imparting flavor and aroma to the finished product. Cottage cheese is a cheese curd product with a mild flavor that is drained but not pressed so that some whey remains. The curd is usually washed to remove acidity. Cream cheese is a soft, mild-tasting, white cheese with a high fat content that is produced by adding cream to milk and then curdling to form a rich curd. Alternatively, cream cheese can be made from skim milk with cream added to the curd. It should be understood that cheese, as used herein, comprises all solid foodstuff produced by the curdling milk.

In another particular embodiment of this invention, the dairy product comprises yogurt. Yogurt generally is produced by the bacterial fermentation of milk. The fermentation of lactose produces lactic acid, which acts on proteins in milk to give the yogurt a gel-like texture and tartness. In particularly desirable embodiments, the yogurt may be sweetened with a sweetener and/or flavored. Non-limiting examples of flavorings include, but are not limited to, fruits (e.g., peach, strawberry, banana), vanilla, and chocolate. Yogurt, as used herein, also includes yogurt varieties with different consistencies and viscosities, such as dahi, dadih or dadiah, labneh or labaneh, bulgarian, kefir, and matsoni. In another particular embodiment, the dairy product comprises a yogurt-based beverage, also known as drinkable yogurt or a yogurt smoothie. In particularly desirable embodiments, the yogurt-based beverage may comprise sweeteners, flavorings, other ingredients, or combinations thereof.

Other dairy products beyond those described herein may be used in particular embodiments of this invention. Such dairy products are well known to those of ordinary skill in the art, non-limiting examples of which include milk, milk and juice, coffee, tea, via, piima, filmjolk, kajmak, kephir, viili, kumiss, airag, ice milk, casein, ayran, lassi, and khoa.

According to particular embodiments of this invention, the dairy compositions also may comprise other additives. Non-limiting examples of suitable additives include sweeteners and flavorants such as chocolate, strawberry, and banana. Particular embodiments of the dairy compositions provided herein also may comprise additional nutritional supplements such as vitamins (e.g., vitamin D) and minerals (e.g., calcium) to improve the nutritional composition of the milk.

In a particularly desirable embodiment, the dairy composition comprises HSG-Extract or a composition comprising HSG-Extract in combination with a dairy product. In a particular embodiment, HSG-Extract is present in the dairy composition in an amount in the range of about 200 to about 20,000 weight percent of the dairy composition.

HSG-Extract or compositions comprising HSG-Extract is also suitable for use in processed agricultural products, livestock products or seafood; processed meat products such as sausage and the like; retort food products, pickles, preserves boiled in soy sauce, delicacies, side dishes; soups; snacks such as potato chips, cookies, or the like; as shredded filler, leaf, stem, stalk, homogenized leaf cured and animal feed.

Additionally, in accordance with still other embodiments of the invention, granulated sugar (sucrose) or other caloric sweeteners such as crystalline fructose, other carbohydrates, or sugar alcohol can be used as a bulking agent due to their provision of good content uniformity without the addition of significant calories.

As used herein, the phrase “anti-caking agent” and “flow agent” refer to any composition which assists in content uniformity and uniform dissolution. In accordance with particular embodiments, non-limiting examples of anti-caking agents include cream of tartar, calcium silicate, silicon dioxide, microcrystalline cellulose (Avicel, FMC BioPolymer, Philadelphia, Pa.), and tricalcium phosphate. In one embodiment, the anti-caking agents are present in the tabletop sweetener composition in an amount from about 0.001 to about 3% by weight of the tabletop sweetener composition.

The tabletop sweetener compositions can be packaged in any form known in the art. Non-limiting forms include, but are not limited to, powder form, granular form, packets, tablets, sachets, pellets, cubes, solids, and liquids.

In one embodiment, the tabletop sweetener composition is a single-serving (portion control) packet comprising a dry-blend. Dry-blend formulations generally may comprise powder or granules. Although the tabletop sweetener composition may be in a packet of any size, an illustrative non-limiting example of conventional portion control tabletop sweetener packets are approximately 2.5 by 1.5 inches and hold approximately 1 gram of a sweetener composition having a sweetness equivalent to 2 teaspoons of granulated sugar (˜8 g). The amount of HSG-Extract in a dry-blend tabletop sweetener formulation can vary. In a particular embodiment, a dry-blend tabletop sweetener formulation may contain HSG-Extract in an amount from about 1% (w/w) to about 10% (w/w) of the tabletop sweetener composition.

Solid tabletop sweetener embodiments include cubes and tablets. A non-limiting example of conventional cubes are equivalent in size to a standard cube of granulated sugar, which is approximately 2.2×2.2×2.2 cm³ and weigh approximately 8 g. In one embodiment, a solid tabletop sweetener is in the form of a tablet or any other form known to those skilled in the art.

A tabletop sweetener composition also may be embodied in the form of a liquid, wherein HSG-Extract is combined with a liquid carrier. Suitable non-limiting examples of carrier agents for liquid tabletop sweeteners include water, alcohol, polyol, glycerin base or citric acid base dissolved in water, and mixtures thereof. The sweetness equivalent of a tabletop sweetener composition for any of the forms described herein or known in the art may be varied to obtain a desired sweetness profile.

Example 1 Preparation of Stevia Extracts

The extraction of Stevia rebaudiana dried leaves was carried out according to method described in U.S. Ser. No. 13/122,232 (Morita et al.).

100 g of dry leaves obtained from Stevia rebaudiana varieties, was extracted several times with 20 times amount of water by weight until the sweetness cannot be tasted. The extract was passed through a column filled up with 300 mL of macroporous absorption resin (Diaion HP-20) wherein the steviol glycosides of the aqueous extract were absorbed to the resin and the majority of other impurities pass through the column without adsorbing to the resin. The resin was sufficiently washed with water to remove the impurities, and the adsorbed steviol glycosides were eluted with 900 mL of methanol. The eluate was passed through a column filled up with 200 mL of ion exchange resin (Diaion WA-30); 10 g of activated carbon was added to the eluate and stirred. The mixture was filtered, the filtrate was concentrated and the residue was dried to give Stevia extract comprising all the steviol glycosides originally present in the dried leaves of respective Stevia rebaudiana variety.

The obtained untreated aqueous extracts were used in various applications without any further purification, crystallization, separation, isolation of individual steviol glycosides.

Example 2 HPLC Assay

Any HPLC method or combination of HPLC methods capable of separating each steviol glycoside described herein can be used. The HPLC assay procedures described by Morita et al., 2011, and Ohta et al., 2010 were unable to separate properly the glycosides such as RebE, RebM, and RebD. Hence a HPLC methodology was developed to reliably determine and quantitate the steviol glycosides RebE, RebD, RebM, RebN, RebO, RebA, Stev, RebF, RebC, DulA, Rub, RebB, and Sbio.

Each sample was analyzed by 2 HPLC methods.

Method 1 was used for analysis of RebE, RebD, RebM, RebN, and RebO, while the Method 2 was used to analyze RebA, Stev, RebF, RebC, DulA, Rub, RebB, and Sbio. The reference standards for RebE, RebD, RebM, RebN, RebO and other steviol glycosides were purchased from ChromaDex Inc. (USA). Agilent 1200 HPLC system equipped with binary pump, autosampler, DAD detector interfaced with “Chemstation B” software was used. Alternatively any other equivalent HPLC system may be used as well.
